Unable to parse filter value

Issue

If you want to filter a multi-target view (e.g. My WorkItems) you may encounter the following error:

Solution

In mutli target views, like MyWorkItems, it is a must that all Type Projections, used by this view, define the same Components with the same Alias names!
In the example above this is issue is caused by the Type Projection itnetX.Views.Operations.PlannedTask.TypeProjection. If you click "Show more.." you will get more information about the error

This error explains that the Type Projection itnetX.Views.Operations.PlannedTask.TypeProjection does not define a Component with the Alias AffectedUser
Let's take a look at this TP using PowerShell:

The faulty Type Projections does not define any Component for Affected User. Lets take a look at another TP used by the same view to get an idea of the Components required:

As you can see, the faulty Type Projection is not only missing the Affected User Component but also CreatedByUser, PrimaryOwner and SLAInstances. If any of those Properties is displayed in a column of the view you will receive another error prompt.

These components must be added with the same alias in order for the view to work properly including filtering
Check in which Management Pack the View is located:

Export the Management Pack and edit the TypeProtection of the affected view.
